This invention relates to roller bearing axle constructions of the type wherein the end portion of the axleis encased in a housing and the roller bearing is interposed between said housing and said axle with its inner raceway member press-fitted on the axle. The principal object of the present invention istoprovidean economical and practical process of removing the roller bearing and its hous- 1 ing from the axle; and also to provide an axle construction whose bearing is particularly adapted for removal according to said process. The invention consists in the process of removing the roller bearing from the axle; 1a and it also consists in the construction, combinations and arrangements of parts hereinafter described and claimed.

Fig, 1 is a longitudinal section through a roller bearing a e construction my invention {and Fig. 2' is a similar embodying section showing parts removed and the axle construction placed in a' press with the ram thereof in engagement with the end of the axle.

so in the accompanying. wings comprises a solid axle 3, with a wheel 4 pressed thereon near its end with the portion of the' axle located outwardly from said wheel extendin intoa cylindrical housing or casing 5 throng The end portion of the axle 3 is rotatably supported in the housing 5 by means of comcal roller bearings interposed between saidas to permit the axle to rock up and-down to take care of low joints in the track.

As shown in the drawings, the roller bearing comprises an inner raceway member 9 v mner walloi e railway axle construction illustrated 1'. v

' ing in the inner end ofsaid housing, w ich a circular opening 6 in the inner wall thereof.

a circumferential rib 12 located about mid way of its length and bearing surfaces that taper from said rib towards the respective ends of said inner raceway member. Cooperating'with each bearing surface is a circular series of conical rollers 13 that cooperate with cups or outer racewa members 14 seated within the housing w ich encases the end portion of the axle. A cylindrical sleeve 15 is pressed on the axle between the hub of the wheel 4 and the-bearing cone 9 with its outer end in abutting relation to the inner end of said cone. The hearing housing 5 serves as a reservoir for lubricant and has its outer end closed by a closure cap 16, which is bolted or otherwise removab ysecured to the housin and-has an inwardly extending annular ange adapted to enter said housing and abut against the end of the outer cup or outer raceway members 14. The inner of the two cups 14 abuts against an annular shoulder formed in the the housing; and the spacing within the axle receiving 0 nsleeve 15 fits opening is provided with annul which 0 erate to prevent the from an the entry of dust into sai housing through said opening. As shown in the drawings the sleeve is made long enou h to extend inwardly beyond the inner ml of' the bearing housingwhen the outer end of the sleeve is in contact with the inner end of the inner raceway member of the roller bearing.

With the above arrangement, when it is desired to remove the roller bearin from-the end of the axle 3, the journal %ox 7, the closure cap 16 and the nut 11 are removed from the .end of the axleconstruction, and the axle construction is then placed in a suitable press with the outer end of the axle 3 in axial alinement with the ram 17 of. the press and with the inner faceof the wheel 4 abutting against a portion of the frame-l8 there ar grooves esca of oil "15 .axle.

The pressure of the ram 17 against the outer end of the axle 3 is then continued and causes the axle 3 to be pushed through ing the axle against movement while pressing the wheel Outward thereon against the inner end of the spacer sleeve which pushes against the cone and thereby strips the bearing, its
